Abstract: Avariable equalizer is described. The variable equalizer provides for independent control of a number of breakpoints in the frequency response of the equalizer so as to allow the equalizer to be readily tuned to compensate for the tilt of coaxial cables over a wide range of characteristic attenuation. In one embodiment, the variable equalizer includes a two port bridge “T” network with variable top and bottom branches that are independently and selectively adjusted to create a desired frequency response. For example, in one embodiment, the top branches include a number of variable RC networks and the bottom branches include a number of variable LR networks. In some embodiments, PEN diodes provide the variable resistance in these LR and RC networks.

Abstract: A monitoring circuit is provided. The monitoring circuit can be used to monitor signals in a cable network. The monitoring circuit includes first and second stages. The first stage has an input and an output. The input is coupled to an external circuit. The first stage scales a voltage received at its input. The second stage is coupled to the output of the first stage. The second stage has a high input impedance and a low output impedance. The second stage buffers a signal at the output of the first stage to an output of the second stage.
